by "normal" do you mean a timeline tween?
if so, there is no one answer that covers all situations except to say you may need to distribute the animation among several layers and timeline tween each layer. tween hints may be needed for some or all the layer timeline tweens.
My hope is to be able to convert the frame by frame animation in a given layer a
"back" to a "normal" motion tween animation.
I would have sworn that I had converted a timeline animetion to keyframes and then had it revert to the "normal" tween state in Flash as is possible in Photoshop.
This would not be "necessary" if I could determine if one can slectively add hieght to the top of the stage.
edited to add image.
my aim is to be able to "re-unite" these single frames in order to move them on the stage minus the grinding tedium of reconstructiong the path of the images they represent accurately.
If your last sentence(s) is a way of saying you want to be able to move all of the frames down (or somewhere) at once, there is a way of doing that. In the bottom of the timeline is a toolbar of sort with some double rectangle icons in it. The one with 2 dark rectangles allows you to move the objects of the entire timeline at once. Just select the icon and then all the frames/layers and mnove them.
If your last sentence is saying something else, you might need to explain it another way
